Police are patrolling St. Augustine, Florida, neighborhoods, announcing through a bullhorn that the area is in a mandatory evacuation zone as Hurricane Matthew approaches the state.

Dana Harrison, who lives on a barrier island across from Anastasia State Park, said she planned to wait out the storm with an out-of-town friend and her cat.

The 57-year-old Harrison says she used to live in St. Thomas and survived Hurricane Hugo in 1989, though the storm destroyed her house. She said she feels more secure in her current home.

About 1.5 million people in Florida have been told to flee inland as the dangerous and life-threatening Category 4 storm makes it way toward the state.

Officials in the Florida Keys say the island chain got lucky and did not receive major damage from Hurricane Matthew.

Monroe County spokeswoman Cammy Clark said any schools, libraries, parks and government offices that had closed would be reopened on Friday.

All roads and bridges in the islands are open. The Key West and Marathon airports will open Friday, though flights may be delayed or canceled due to the hurricane's effects elsewhere.

Coastal waters throughout the Keys were expected to rise up to 2 feet above ground, flooding some neighborhood roads but not the narrow Overseas Highway that links the islands with Florida's peninsula.

At the Kennedy Space Center in central Florida, NASA and the private company SpaceX are taking precautions to protect their capsules and rockets.

SpaceX has been counting on Kennedy's historic Launch Complex 39A to get its rockets flying again, hopefully in November.

SpaceX's pad at neighboring Cape Canaveral Air Force Station was damaged Sept. 1 when a Falcon rocket exploded during prelaunch testing.

NASA, meanwhile, has secured a new Orion capsule currently in development in a secure Kennedy building designed to withstand sustained wind of 114 mph and gusts of 125 mph. The capsule will be used to launch astronauts beyond low-Earth orbit.

NASA's Kennedy Space Center is closed Thursday and Friday, with a 116-person ride-out crew on duty to help keep things safe.

The Cape Canaveral Air Force Station also was closed to nonessential personnel.

Turns out this wasn't the best week to plan a cruise -- at least for those who signed up to float from Baltimore to the Bahamas and the Turks and Caicos on the Carnival Cruise line's Carnival Pride.

A total of 1,600 passengers bought tickets for a seven-day trip to Freeport and Half Moon Cay in the Bahamas, and the island of Grand Turk in the Turks and Caicos. The ship was rerouted at the last minute before it set sail Sunday, and instead of going to the Caribbean, headed north to New York.

After it left the Big Apple, the ship was supposed to make a stop in Saint John, New Brunswick, before heading south back to Baltimore. But because of heavy weather conditions, it was forced to enter the Chesapeake Bay. It is now scheduled to arrive back in Baltimore next Sunday.

Annette McKenny Neufeld of Ontario, Canada, is one of the disappointed passengers.

Neufel had been dreaming about a tropical beach vacation, but after several days aboard the rerouted ship, she says the only thing she wants "is to get off and head home."

Neufeld shared her thoughts with The Associated Press through Facebook Messenger on Thursday, while still 478 nautical miles from Baltimore's harbor.

Charleston Mayor John Tecklenburg says that although the city that draws millions of tourists a year is known widely for its hospitality, he wants everyone to leave town as Hurricane Matthew approaches.

City officials warn that the heavy rains and storm surge from Matthew could combine to cause flooding worse than the floods the city saw a year ago.

During a news conference Thursday afternoon, Tecklenburg asked residents to pack up what they need, secure their property and get out of town.

City officials say that the first rains from the storm are expected to move in late Friday and conditions will deteriorate into Saturday.

Police Chief Greg Mullen warns that at the height of the storm, police and emergency personnel will be pulled off the streets and there won't be the usual rapid response to 911 calls.

The National Weather Service is posting flash-flood watches for the entire South Carolina coast and warning that the combination of storm surge and rains from Hurricane Matthew could cause worse flooding in downtown Charleston than the October storm of a year ago.

During the October 2015 flooding, the city was closed for several days.

Forecasters are posting flash-flood watches on the coast from Friday morning through Saturday night.

An advisory warns that 8 to 14 inches of rain are expected with locally higher amounts. It said residents should be prepared for the possibility of widespread street flooding and property damage on the Charleston peninsula.

Forecasters say the storm could bring severe flooding even though the center of Matthew is expected to stay offshore.

President Barack Obama has declared an emergency in the state of Florida and has ordered federal aid to supplement state, tribal, and local response efforts to Hurricane Matthew.

Obama's action authorizes the Department of Homeland Security and the Federal Emergency Management Agency to coordinate efforts to alleviate the suffering caused by the hurricane. The directive applies to more than two dozen counties in Florida.

Emergency declarations are designed to help provide emergency services to protect lives and property, and to lessen the threat of a catastrophe.

Airlines are canceling hundreds of flights as Hurricane Matthew pelts the Florida coast with high winds and heavy rain.

The Fort Lauderdale airport shut down on Thursday morning, and farther north the Orlando airport expected to do the same by nighttime.

Before 2 p.m. Eastern time, flight-tracking service FlightAware.com reported that 1,500 Thursday flights within the U.S. had been scrapped, with the largest numbers at Fort Lauderdale and Miami. American Airlines, which has a major hub in Miami, was the hardest-hit carrier, followed by Southwest Airlines and JetBlue Airways.

FlightAware said airlines had already canceled 1,300 more flights scheduled for Friday. Delta Air Lines said cancellations were likely to spread to coastal Georgia and South Carolina on Saturday.

Airlines often cancel flights before storms hit to prevent passengers from being stranded at airports and to keep their planes in position to recover after the bad weather passes.

Disney officials said on the company's website Thursday afternoon that theme parks, water parks, Disney Springs, the miniature golf course and the ESPN Wide World of Sports Complex would close at 5 p.m. The theme park will remain closed through Friday.

Alyson Lundell is director of public relations for Universal Orlando. She said in a statement that Universal Studios Florida, Universal's Islands of Adventure and Universal Citywalk would close at 5 p.m. and remain closed on Friday.

Earlier Thursday, SeaWorld announced on its website that the park would close at 2 p.m. and remain closed on Friday.

The death toll in Haiti from Hurricane Matthew has risen to at least 108.

Interior Minister Francois Anick Joseph announced the figure in the capital on Thursday as authorities and aid workers work to gauge the extent of the deaths and damage in the impoverished country.

Details on the deaths were not immediate available.

Previously, officials said there had been at least 23 deaths from the storm in Haiti. There were also four people killed in the neighboring Dominican Republic, one in Colombia and one in St. Vincent and the Grenadines.

Hurricane Matthew roared across the tip of the peninsula on Tuesday but authorities have struggled to reach people in the most remote areas including around the town of Jeremie and throughout the Grande Anse area.

Forecasters at the National Hurricane Center are warning that large waves pushed by Hurricane Matthew could threaten lives and property hours before the Category 4 storm's eye nears the shore.

Jamie Rhome is leader of the storm surge team at the hurricane center in Miami. Rhome says levels were up to a foot higher than normal as far north as Jacksonville on Thursday as a strengthening Matthew tore through the Bahamas toward Florida.

Rhome said parts of Florida, such as the Cape Canaveral area or communities along the St. Johns River, could see waters rise up to 9 feet above ground -- a level well overhead for most adults.

Rhome says such levels are life-threatening because they are accompanied by "waves and currents and floating debris."

The hurricane center has issued storm surge watches and warnings for life-threatening flooding from Boca Raton in South Florida all the way up the coast north of Charleston, South Carolina.

12:30 p.m.

Forecasters are warning that Hurricane Matthew could inundate the coast of South Carolina just a year after what was called a 1,000-year flood closed Charleston for several days.

A forecast map issued by the National Weather Service shows that as much as 14 inches of rain could fall in the Charleston and Georgetown areas between Thursday night and Sunday night as the hurricane passes at sea.

It was just a year ago that as much as 2 feet of rain fell in some areas of South Carolina. Streets in Charleston were flooded so badly that police kept people from coming downtown to the peninsula for several days.

A section of Interstate 95 near Orangeburg was also closed for a time. The Matthew forecast predicts between 5 and 8 inches of rain could fall in that area before the weekend is over.

11:45 a.m.

Haiti's Civil Protection Agency says the death toll from Hurricane Matthew is now at 23.

The agency tweeted Thursday that in addition to the deaths, three people were missing, 27 injured, and more than 21,000 people were in 152 shelters. The statement did not give any details about the deaths in a brief statement.

Authorities and aid workers were still trying to reach remote areas of the peninsula to get a full accounting of the damage.

The updated toll brings the total number of deaths to at least 29 in the Caribbean from Hurricane Matthew. In addition to the 23 in Haiti, there were 4 in the Dominican Republic, 1 in Colombia, and one in St. Vincent and the Grenadines.

The White House is imploring Americans in areas affected by Hurricane Matthew to follow any evacuation orders given.

White House spokesman Josh Earnest says the Category 4 storm's impact is likely to be "quite significant." He says the White House is strongly encouraging people to heed the warnings and instructions given by local officials.

Earnest is also urging people to stay abreast of the latest weather forecasts. He said Thursday was a "pivotal day" for preparations, as some parts of the Florida coast were expected to experience tropical storm conditions as early as the afternoon.

President Barack Obama received his latest update about hurricane preparations on Thursday morning.

He said anyone living in low-lying areas or on barrier islands should "evacuate, evacuate, evacuate." He says tolls have been lifted on all roadways to help make evacuations easier. Scott says more than 1.5 million people are living in evacuation zones.

Remarking that "this is game day," Scott warned people to stay off beaches up and down Florida's Atlantic coastline Thursday, adding that "no one needs to be on the beach doing anything."

The governor has activated another 1,000 National Guard members, bringing the total to 2,500. He says they'll be available to help with evacuations and getting people to shelters.

Deal said Thursday that everyone east of Interstate 95 should flee Georgia's six coastal counties -- Chatham, Bryan, Liberty, McIntosh, Glynn and Camden. Those counties have a combined population of more than 522,000 people.

The governor had asked coastal residents to evacuate on a voluntary basis Wednesday. He called for mandatory evacuations as the National Hurricane Center placed all 100 miles of coastal Georgia under a hurricane warning Thursday.

Officials say powerful winds and heavy rains from Matthew could begin to arrive in coastal Georgia late Thursday. The storm is forecast to pass Saturday.

The Georgia coast hasn't seen a hurricane evacuation since a near-miss with Hurricane Floyd in 1999.

Hurricane Matthew has strengthened to a catastrophic Category 4 storm as it barrels toward the heavily populated coast of Florida.

The National Hurricane Center in Miami said the storm's maximum sustained winds had strengthened to 140 mph as of late Thursday morning and were expected to maintain their strength as the storm approaches the Florida coast.

Hurricane conditions were also still affecting the Bahamas. The storm was expected to start affecting Florida by early afternoon Thursday.

10 a.m.

Gov. Nikki Haley says parts of two counties along South Carolina's northern coast are being evacuated ahead of Hurricane Matthew.

Haley warned anyone in an evacuation zone not to take the orders lightly. She says surge from the storm could be as high as 8 feet and affect not only the coast but also areas farther inland.

So far, Haley says 175,000 people have evacuated from the coast. On Wednesday, the state reversed the eastbound lanes of Interstate 26 from Charleston to Columbia, allowing more motorists to move inland at once.

Forecasters say they expect Matthew to strengthen to a Category 4 hurricane before making landfall in Florida, turning north and passing just off the South Carolina coast late Friday or early Saturday.

North Carolina Gov. Pat McCrory says the latest predictions show that his state will avoid a direct hit from Hurricane Matthew.

But emergency workers are continuing to prepare for high winds, rain and storm surge.

McCrory says North Carolina cities like Jacksonville and Morehead City could still see wind gusts of up to 60 mph beginning Saturday. Widespread power outages are possible. There could be a foot of rain in some areas.

The National Hurricane Center in Miami says the hurricane is strengthening and called it dangerous and life-threatening. About 1.5 million people in Florida have been ordered to evacuate.

The head of the Bahamas National Emergency Management Authority says the capital Nassau is now receiving the full brunt of Hurricane Matthew.

Capt. Stephen Russell says there are many downed trees and power lines but no immediate reports of significant flooding or casualties as of early Thursday. Russell says Nassau should feel the full effects of Matthew for much of the day.

"We are experiencing the brunt of the hurricane force winds now so we just have to wait and see how we fare over the next five of six hours," he told The Associated Press.

Nassau is on the most populous island of New Providence in the central Bahamas. The streets were deserted as palm fronds flew through the air under heavy rain. Those in Nassau without generators are without power because authorities shut down the power when winds reach 40 mph to protect the grid. The major tourist hotels are on generator power.

The storm is now clear of the lightly populated islands of the southern Bahamas and Russell says there are no reports of any significant damage or casualties on those islands.

In Daytona Beach, the owners of the Sahara Motel refunded money to four remaining guests and were finishing securing their property as Hurricane Matthew roars toward Florida's coastline.

Laura Axelsen says the winds are getting stronger Thursday morning as they finish boarding up windows at the two-story, mom-and-pop motel that sits across the street from the Atlantic Ocean.

She says they stopped renting rooms two nights ago, but normally rent about 40 rooms per night.

Her father, Ray Gohill, has owned the motel for 38 years.

Axelsen says the motel had extensive roof damage in 2005 when they were hit by three storms.

Once they secure the motel, Axelsen says they'll be heading to a safer area to ride out the storm. She says the motel has nothing to block it from the winds. There are no larger hotels across the street on the beachside of Atlantic Avenue.

City officials in Charleston, South Carolina, which weathered Category 4 Hurricane Hugo almost 30 years ago, say the city has run out of sandbags after distributing more than for any other storm.

The city has distributed more than 15,000 sandbags as residents prepare for Hurricane Matthew. There were long lines of motorists waiting to get sandbags at one distribution point on the city's north side late Wednesday.

Charleston is prone to flooding even in summer thunderstorms and if people need to sandbags now, they will have to get them at hardware or home stores.

The upscale community of Kiawah Island southwest of Charleston plans to close at noon Thursday when officials barricade the entrance to the gated community. Fire and emergency equipment will be moved to the mainland.

State regulators are urging dam owners in South Carolina to begin reducing the water levels in their ponds and lakes.

The Department of Health and Environmental Control said Wednesday that water levels behind the dams should be reduced before rains come from Hurricane Matthew.

Dam failures one year ago caused and worsened flooding that hit central and coastal South Carolina last October. Some parts of the state got 20 inches of rain in one day last year.

Hurricane Matthew is not expected to bring that much rain to most sections in the date, but the state agency warms the rains could still cause problems with the dams.

State officials also are reminding owners of dams to notify those with dams farther downstream they are releasing water.

The murder trial of a man accused of intentionally leaving his toddler son in a hot SUV to die is being put on hold as Hurricane Matthew heads toward the Georgia coast where the man's being prosecuted.

Local news organizations report a judge said the trial of Justin Ross Harris would be in recess Thursday and Friday and resume Monday.

Prosecutors have said Harris intentionally killed his 22-month-old son, Cooper, by leaving him for hours in a vehicle parked outside the father's workplace in Cobb County near Atlanta. Cooper's lawyers say the death was accidental.

The trial was moved to Brunswick on the coast because of pretrial publicity.

Georgia Gov. Nathan Deal on Wednesday urged residents of several coastal counties, including the one where Brunswick is located, to evacuate.

Forecasters say Hurricane Matthew has gained new muscle over the Bahamas and they are also expanding the hurricane warning area further up the Southeast Atlantic seacoast from Florida into Georgia.

The U.S. National Hurricane Center in Miami says Matthew's top sustained winds have risen from 115 mph (185 kph) to 125 mph (205 mph) in just a few hours early Thursday as the storm continues to batter the central Bahamas.

The center says it is extending a hurricane warning area already covering a large swath of Florida's Atlantic coast further northward to Altamaha Sound, Georgia. It also says a newly expanded hurricane watch now extends from the Altamaha Sound up the coast to the South Santee River in South Carolina.The center added in its 5 a.m.

Thursday update that Matthew should gain further in intensity over the next day or so and is forecast to become a Category 4 storm as it approaches Florida's Atlantic coast.

Matthew's center is now about 255 miles (410 kilometers) southeast of West Palm Beach, Florida, and moving northwest at 12 mph (19 kph) over the Bahamas.

Forecasters say Hurricane Matthew is now pounding portions of the Central Bahamas and is expected to strengthen as it approaches Florida.

The U.S. National Hurricane Center in Miami said Matthew remains a powerful Category 3 storm with top sustained winds of 115 mph (185 kph) as of 2 a.m. EDT Thursday. It added that Matthew is expected to intensify over the next day or so and is forecast to again become a dangerous Category 4 hurricane as it nears Florida's Atlantic coast.

Matthew was briefly a very dangerous Category 5 storm on its march across the Caribbean. By early Thursday, Matthew was centered about 295 miles (480 kilometers) southeast of West Palm Beach, Florida. It also was about 100 miles (160 kilometers) south-southeast of Nassau in the Bahamas.

The Miami forecasting center said no changes have been made to the existing hurricane and tropical storm warnings and watches as of 2 a.m. EDT.
